Hi everyone! I got a big problem at hand. In two months a good buddy of mine is going to get married and asked me if I could shoot some nice pics for him. He knows that I have a nice camera and do relativitly (sp?) good pictures. But a wedding is a whole different thing for me. Most of the time I shoot party pictures or still life in fairly decent light. And now you guys & gals come into play. I currently have a Pentax K10D, the 18-55mm kit lens, a 50mm F1.4 lens, some memorycards, two batteries. I'm going to buy a tele lens and a flash - which one I don't know exactly. The lens I was looking at was the Sigma 70-200 EX HSM one, because of the silent focusing. An alternative would be the Pentax DA* 50-135, but I have the feeling I might be lacking some outreach. Has anybody a hint for me? As for the flash, I'm totally dumb. Normally I would crank the ISO setting up to 640 and use my 50mm lens - so any help there would be neat too. Possible choices are the Pentax 540, Sigma 530 Super oder the Metz 58 AF. Budgetwise I'm pending around 1k euro for both items and other stuff like baggage. I feel quite honored that he wants me to accompany the paid shooter, but I'm also afraid I might not be up to the task. Any proficient wedding photogs here who are willing to help me? I'm really looking forward for any insight or tips.
